A small appellation located on the east bank of the river in the heart of the Rhône Valley, Coteaux du Tricastin is a relatively new wine region, with production only starting in the last 50 years or so. The wines are generally lighter in body than the more well-known appellations to both the north and the south, but quality levels have risen in the last decade as more producers eschew the older traditional grapes in favor of the more internationally loved varietals.
The soil is similar to that of Châteauneuf-du-Pape, with many of the galet stones covering the area, absorbing the heat of the day only to release it during the evening to the benefit of the vines. Both red and rosé wines are created from primarily Grenache, Syrah, Cinsaut and Carignan, though other traditional Rhône grapes and even up to 20% white varieties are allowed into the mix. White wines made from Viognier, Roussanne and Marsanne are increasing in quality, and bringing the reputation of Coteaux du Tricastin along for the ride.
